Fig. 5From: Ultrasound-driven piezoelectric current activates spinal cord neurocircuits and restores locomotion in rats with spinal cord injuryNormalized AUC and Vpp of MEPs collected from all healthy rats (n = 5) for 3 weeks post-surgery. Recruitment curves of AUC and Vpp with increase of acoustic intensity indicate increase in movement strengths via pES current. C equals 0.003 mW/cm2 for pESBack to article page
